T all whom it may concern:

Be it known that we, CARROLL BEALE and DAVID P. MooRE, citizens of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Hydraulic Turbine-Valve-Operating Mechanism, of which the following is a specification, reference being had therein to the accompanying drawmg.

, Our present invention relates to improvements in hydraulic turbine valve operating mechanisms, and has special reference to a class of turbine operating mechanisms for large gate valves, as are used in the art of water distribution, said mechanism being so constructed as to employ the water pressure in the main, to either close or open the valve, and which will operate in the vault if water therein is high enough to submerge the valve and motor.

To attain these objects, we employ a reversible water turbine motor, which is operably connected to the valve casing within a v with the bypass 4.

. close the i I vault so as to receive the pressure from the main or the valves by-pass to operate the turbine, which in turn is operably connected to the valve closing and opening mechanism, the turbine being operated forwardly to valve .and reversed to open the valve. 1

To clearly illustrate the invention, referonce is had to the accompanying drawings,

'in which va-tion. Fig. 3 is a top plan view thereof. Fig. 1 1s a vertical central section through the turbine on line .r.r, Fig. Fig. 5 is a horizontal section on line y.y, Fig. 4. Fig. 6 is an elevation of the turbine wheel. Fig. 7 is an elevation of the turbine, looking toward the entrance end. Fig. 8 is a similar view looking toward the discharge end. Fig. 9 is a bottom plan of the casing, modified form of gearing. elevation thereof.

Referring to the drawings :The numeral 1 designates the vault and 2, the valve, which is connected to the main 3, and is provided 'These valves are commonly provided with the key shaft 5, carryin the small pinion 6, which meshes with the v-a lves main operating gear or pinion 7.

Fig. 10 is a s ide illustrating a.

the controlling valves 11 a or 11 is operated,

the water is projected into the turbine casing through the respective nozzle, and discharges through the discharge 12. and the enlarged pipe 13, where it may be conducted to either the trap a,v or any other desired place. Mounted rotatably within the casing is the turbine wheel 14, which may be of any preferred form, as circumstances may demonstrate or require, but as here shown consists of the hub 15. having the disk 16 carrying the integral periphery 17, the said hub and periphery being incased by means of the top plate or disk 18 and the bottom plate or dis 19, as clearly shown in Figs. 4 and 6. Secured circumferentially to the periphery and between the projecting edges of the disks 1S and 19, are the blades 20, which may be perpendicular. or as shown slanting or inclining at an angle of about 10 degrees the incline being so arranged that the forward'or valve closing nozzle 9. will be slightly more eflicient than the reverse or valve opening nozzle 9, it requiring more force to close than open the valve. Keyed to the hub, is a shaft 21, whose lower end is provided with a shouldered socket 22, for the reception of the key shaft 5, while upon the upper end is mounted the balancing and starting or final closing wheel 23, which as inferred from its name may be used if necessary to start the valve toward closing and finally closing the same, or while when the turbine wheel is rotating acts as a balance. wheel. end is also shouldered as at b so that a key may be employed from the. manhole above. In order that the turbine wheel will rotate freely and as frictionless as possible, we provide the thrust bearing 24, interposed between the lower projecting end of the hub and the thrustbearing casing 26 of the casing. Any construction of su port that may rove efficient may be einpl oyed for the turiiinecasing, but we prefer to employ the sectionalIsleeve 27, having the supporting flange 28, to which is connected the standards or The extreme upper legs 2 9, which are in turn connected to the underside of the casing, this construction being clearly shown in Figs. 1 and 2.

In the drawings, Figs. 9 and 10, we illustrate a form of gearin whereby the turbinemay operate larger va ves, the lower end of the shaft being rovided with a small pinion or gear 30, whic 1 meshes with the large gear. or pinion 31, journaled in the casing 32, and having the key-shaft receiving shouldered socket 33, whereby the key-shaft 5 is enaged. The advantages of this will be readithat we rovidea very simple and thoroughly practica valve closing and opening mechanism, which has all the advantages of the electric motors, and none of its disadvantages, as the power to operate our mechanism is always where needed, being the water in the main and by-pass, and as our mechanism will operate successfully even though the vault may be flooded, the various parts of' the controlling mechanism being accessible e ther through the man-hole or the pipes located in the vault above the said parts.
